Robotic arms have evolved rapidly over the past decade, integrating advanced control algorithms, lightweight materials, and artificial intelligence to perform diverse tasks across industries. This review paper provides a comprehensive overview of robotic arm development, including design structures, kinematic modeling, control methodologies, and multi-domain applications. By synthesizing findings from recent studies, this paper highlights innovations such as compliant joints, twin actuation systems, hybrid control mechanisms, and modular collaborative designs. Applications in industrial automation, medical surgery, space exploration, and precision agriculture are critically analyzed. Finally, challenges and research directions are discussed to promote further development in efficiency, adaptability, and intelligence of robotic arms.
Introduction
Robotic arms are key automation innovations, mimicking human limb functions across industrial, medical, agricultural, and space applications. Research focuses on improving dexterity, stiffness, precision, and energy efficiency while maintaining lightweight structures. Designs include snake-arm robots for confined spaces, dual-arm collaborative robots, and compliant manipulators for safe human interaction.
Control strategies involve robust sliding mode, hierarchical, and AI-based controllers, often optimized with algorithms like PSO. Applications span industrial assembly, surgical procedures, space debris handling, and agricultural tasks such as pollination. Emerging trends include compliant and modular designs, AI integration, and multi-arm collaboration. Future directions emphasize deep learning, sensor fusion, digital twins, and lightweight, energy-efficient structures for enhanced adaptability and performance.
Conclusion
This review consolidates developments in robotic arm design, control, and applications across multiple domains. The integration of compliant mechanisms, hierarchical control, and advanced simulations has transformed robotic arms from rigid manipulators into intelligent, flexible systems. Continued interdisciplinary research will drive innovation, making robotic arms indispensable in future industrial, medical, and extraterrestrial environments.
